A customer reports their hosts are performing slowly after migration to a new VMAX array. You
review performance data from the VMAX and note the following:
– I/O sizes are 16 KB.
– The front-end director ports are operating at 1 GB auto-negotiate.
– Several front-end director ports are approaching 100% utilization.
– A few director ports show little or no utilization.
What do you advise the customer?

A.
Rebalance the hosts across all available FA ports and consider upgrading the SAN switch ports
to 2 GB or higher.

B.
Reduce the number of hosts that are accessing the VMAX and consider implementing iSCSI
connectivity.

C.
Rebalance the hosts across all available FA ports and consider setting the front-end director
ports to 2 GB or higher.

D.
Add more HBAs to each host accessing the VMAX and consider setting the host I/O size to 8
KB or less.
